windows 98 as a vpn server?

Let me start of with I have never setup a VPN server on a windows 98 machine. You can use Windows 2K pro which should install no problem on your 98 machine, its minimum requirements is Pentium with 64MB ram and 2GB HDD, slow but runs fine. If thatis not an option try Linux or FreeBSD. You will beable to run either of those OS'. FreeBSD is use more for security implementations than Linux and has much of what you are looking for built in. For instance, ssh (Secure Shell). With SecureCRT you can redirect local ports to the server. creating secure tunnels for your applications. And far cheaper then a commercial solution for your project.

Don't do it. Even if you can. You are talking about setting up a security device. A KEY device. The one that if it is compromised, your entire VPN tunnel is potentially in the clear. You'll be computing away, oblivious to the fact that 14 year old Ronnie down the block is stealing your private information.

Winodws 98 is anything but secure. You will want to harden this VPN device so much so that it bounces data back at any hackers that ping your way. If you are going to start with auseless OS that can be compromised by SO-O-O-O many exploits, why bother using VPN at all?

Put it this way. If every GM car could be unlocked and started with any GM key, would you rush out and buy one and feel secure because the doors lock automatically? Spend the money and get the Ford Mustang. Or at least do W2K on your lemon. C'mon. You know you want to... (And don't use it for ANYTHING else. Not even solitaire!)
